Southern California Edison TLRR - 500 kV

Two Single Circuit 500 kV towers were raised 10ft & 15ft and were completed in a total of 10 days.

Completion of Nuclear Energized Tower Lift - 345kV

Ampjack successfully completed the first energized mid-tower lift on a 345kV nuclear-powered transmission line – the first in the country.

Western Area Power Authority 230 kV Double Circuit Tower Raise

Ampjack Industries Ltd. completed 40 tower raises on 230 kV double circuit transmission lines for Western Area Power Authority Upper Great Plains region during the Fall and Winter of 2015/16.

Glenbard AMPJACK® Test Tower

Performance Acceptance testing of AMPJACK^® Tower Raise System on Un-balanced Dead-End Structure.

SaskPower - Energized 230 kV Double Circuit Tower Raise Project

This was Ampjack’s first raise project in Canada. Phase 1 was completed in 2015, 26 lattice structures of two tower types were lifted in 5’-0" or 2'-6" increments to total 7'-6", 10’-0", 12'-6" and 15’-0" raises.

NERC Compliance Can Be Challenging

The New York Utility Owners required more ground clearance to maintain safe operation on their lines.

The AMPJACK® Tower Lift System

Advanced Technologies for a Better Solution

The AMPJACK^® lift system is essentially a "Crane in a Box" — deployed by a small crew, virtually anywhere in the world. It is fully modular and is engineered to lift just about any tower design — from simple, single circuit towers to complicated, multiple circuit towers. Utilizing a simple-to-install and simple-to-operate custom hydraulic system, the Ampjack mounts inside the body of the transmission line tower — a safe working zone for the crew where limits of approach are a concern.

Once installed on the tower, the AMPJACK^® takes the entire load of the tower section and conductor which the tower supports and then raises it to the utilities specified amount. Once the tower is lifted, new tower framing is bolted in place and the Ampjack is removed from the tower. This means the tower can be raised without de-energizing the existing line, saving costly outages during the raising of the tower.

Benefits of AMPJACK^®

The AMPJACK^® Tower Lift System provides high-voltage transmission utilities a solution to raise tower lines without taking an outage; effectively optimizing power line resources, maximizing capacity and satisfying the growing demand for power around the world.

With the ability to safely lift the towers while the lines are energized, the utility saves costly outages, outage planning, contingency planning and scheduling while maintaining system reliability.

Single Circuit 345 kV

Eco-Friendly

Using the AMPJACK^® lift system, a crew of 8–10 qualified personnel and a small number of standard trucks are needed to complete the tower raise, the entire AMPJACK^® lift system is packaged in 8–12 custom job boxes which are easily transported with a light flat deck trailer.

It can be transported over just about any trail, roadway, or right-of-way that would otherwise be inaccessible by large cranes and heavy equipment. Since the entire system is modular, the Ampjack can also be heli-lifted to the locations when towers aren't accessible by road. Using the AMPJACK^® lift system can greatly reduce the environmental permitting process and expedite the construction plan and reduce permitting and ROW access costs.
